Foldable Stroller Wagon With Nesting Handles and Frame Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stroller wagons with both pushing and pulling modes do not compactly store handles, leading to increased footprint and untidy appearance due to hanging handles and bulky soft goods attachments.
Innovation Solution
A foldable wagon assembly with pivotally attached handles that nest or telescope when not in use, and a sleek attachment system for soft goods using slots and stiffeners to secure the soft goods assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If handles are left to hang or lay on the ground when not in use, then the stroller wagon can be operated in both pushing and pulling modes, but the footprint of the stroller wagon increases
Solution Approach 1:
The push handle is configured to nest within the receiving area of the frame when not in use, specifically positioning the handle within the cargo storage space. This nesting arrangement allows the handle to be stored compactly without increasing the overall footprint of the stroller wagon, while still enabling both pushing and pulling modes when needed
2Reliability
If soft goods attachments wrap around the wagon frame with fasteners, then the soft goods can be secured to the frame, but the appearance becomes untidy or bulky
Solution Approach 1:
The patent removes the traditional fastener system and wrapping configuration, instead integrating soft goods attachments directly into the frame structure through dedicated attachment points. The soft goods are secured using integrated clips or fastening mechanisms that are built into the frame, eliminating the need for external wraps and visible fasteners, thus maintaining a sleek appearance while ensuring secure attachment
Solution Approach 2:
The soft goods attachment system is merged with the frame structure itself, where attachment points and securing mechanisms are integrated into the frame design. This consolidation eliminates separate wrapping components and visible fasteners, creating a unified streamlined appearance while maintaining secure attachment functionality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Minimizes the stroller's size and provides a streamlined appearance by storing handles and securing soft goods efficiently, enhancing user experience and aesthetics.
Implementation Method 1
A second handle can be pivotally connected to a portion of the frame. The second handle is configured to pivot between: a stowed position in which the second handle nests relative to at least one portion of the frame; and a deployed position in which the second handle extends upwards from the frame.

AI summary
A foldable wagon assembly is disclosed herein including multiple features. In one aspect, a push handle is provided that includes pivoting connections located inward from a longitudinally outermost edge of a frame of the wagon. In another aspect, an upper end of the frame includes at least one slot for securely attaching a soft goods enclosure to the wagon. A pull handle is also provided that can be securely attached in a generally upright position via a retention clip formed on the frame of the wagon.
